Unfortunately Instagram cuts off the full length of the video due to having a limit of one minute for videos. The full video is available on her official (and public) Facebook page.
One can also see the one remaining foredeck crane (from 1992 onwards) being relocated (very briefly in one of the time-lapse scenes and by a drydock crane) from it's previously normal port side position to the opposite position, reusing the stump of the original-from-build starboard side crane (as removed in 1986/7) but now leaving a stump on the port side instead. It is good to see it will be reused given her starboard side is alongside now.
I can't tell, however, if the steel letters that made up "Southampton" have been removed and painted over as the outline of some of the letters appears to be visible but without the embossed type effect produced by the steel letters going over the hull at that point. Would be interesting to confirm either way.
